Redis is an open-source, in-memory data store commonly used as a cache, message broker, and NoSQL solution thanks to its low latency and rich support for data structures.
Redis provides a variety of data types - such as strings, lists, hashes, sorted sets, JSON, time-series, and probabilistic structures - along with advanced features like transactions, pub/sub, and clustering.
Originally created in 2009 to offer a scalable data store with more operations than simple key-value access, Redis has since become one of the most popular databases worldwide, especially where low latency and scalability matter. It has an active community, official clients for most programming languages, and ongoing development through Redis Ltd.
With modules and extensions, Redis can now handle vector search, full-text search, geospatial data, time-series, and more - making it a comprehensive platform for real-time data handling.
